M. R. James and That Which Creep Like Shadows...

An interesting study of the works of M.R. James from the Guardian:

The "ominous thing" in James's stories, written between the 1890s and 1930s, might be a sheeted ghost (Oh, Whistle, And I'll Come to You, My Lad), a corpse crawling from its grave (The Mezzotint), or something grotesque and tentacular (The Treasure of Abbot Thomas). Whichever form it takes it will be malevolent and capable of killing. There are no Caspers to be found here.
... Much of James's skill as a writer resides in his talent for evoking a sense of place - particularly when writing about the East Anglian countryside he knew as a child – and an often perfect judgment of what to reveal and when. The stories thrive, too, on their scholarly depth and his knowledge of folklore. His characters are for the most part antiquarians who, through intellectual curiosity, stumble into the unknown. Frequently James will wrap a web of quotations, footnotes and references to historical documents – both fictional and real – around his stories (he begins one with a block of Latin), giving them not only an air of authenticity but also an essay-like quality, so that the expertly handled intrusion of horror arrives all the more powerfully.
